AC Milan need to enforce their defense, and considering the difficulties to obtain Montpellier 23 year old Mapou Yanga-Mbiwa, could swoop on Marseille 22 year old Nicolas Nkoulou, but to obtain the Cameroon international, valued about 15 million euros, the rossoneri will have to compete, according to Metro, with Chelsea and Barcelona; but the most shockinh rumour regards Montreal Impact 36 year old Alessandro Nesta, who, according to Sportmediaset, could join his former team in January. Still regarding the defense, according to the German press, the Lombard club, as well as AS Roma, are keen on Bayern Munich 27 year old right back Rafinha, while 26 year old Cristian Zapata, on loan from Villarreal, if he won’t be signed on permanent deal by the rossoneri, could move, as confirmed by his agent to Protransfers.ru, to Zenit St. Petersburg or Anzhi Makhachkala. Milan are also seeking an attacking midfielder and are interested in Manchester City 22 year old Vladimir Weiss, actually on loan at Pescara.
